# OEM parts, and how to find your data plate

Updated: 2026-08-13

One appliance model can span several parts revisions. The serial number is what selects the right one, which is why we ask for it before the van is loaded.

Every service call we take begins with the same request: the model and the serial
number off the data plate. It sounds like paperwork. It is the single biggest
factor in whether your repair takes one visit or two.

## Why the serial matters more than the model

A model designation can stay on the market for years while the parts inside it
change. Suppliers revise a valve body, a fan motor, a board firmware level or a
hinge, and from a given production date onward the correct part number is
different even though the badge on the door has not changed. The serial number is
what encodes when your specific unit was built, and therefore which revision it
takes.

Order by model alone and you have a reasonable chance of receiving a part that
almost fits — the connector is different, the mounting boss has moved, the
resistance value is not the same. That is a second visit and a return shipment,
and it is entirely avoidable.

## Where the plate is

| Appliance | Usual location |
| --- | --- |
| Built-in refrigerator or freezer | Upper left interior wall, or behind the base grille |
| Undercounter or wine cabinet | Interior side wall, or on the frame behind the door |
| Range or rangetop | Behind the kick panel, or on the frame behind an oven door |
| Wall oven | Door frame, visible with the door open |
| Dishwasher | Edge of the inner door panel, visible with the door open |
| Ventilation hood | Inside the canopy, above the filters |
| Outdoor grill | Underside of the control panel, or inside the cart |

A phone photograph of the plate is worth more than a transcription. Serials get
mis-read — ones and sevens, zeros and the letter O — and a photograph removes the
argument entirely. Send it with the booking and we can check parts availability
before we come out rather than afterwards.

## What OEM buys you

We fit genuine OEM parts, and the honest case for that is not brand loyalty. It
is three practical things.

**Dimensional and electrical match.** A control board with the same footprint and
a different firmware level will run a motor at the wrong speed or misread a
sensor curve. Aftermarket sensors in particular are frequently close rather than
correct, which produces an oven that is accurate at one temperature and wrong at
another.

**Warranty that means something.** We give 90 days on labour and 365 days on
parts. That is only underwritable on parts with a real supply chain behind them.

**Diagnosis stays honest.** When a repair fails after an OEM part, the diagnosis
was wrong and we own it. When a repair fails after a generic part, nobody can
tell which of the two it was, and the customer pays for the ambiguity.

## Lead times, said plainly

Some parts are stocked and some are not. Control boards and door assemblies are
the two categories most likely to sit on an extended lead time, and August is the
month when the most people need them at once. The estimate carries a realistic
date rather than an optimistic one, and if a part is genuinely unavailable we say
so instead of leaving your appliance in pieces while we hope.

Where a part is obsolete, we tell you that too, along with what the options
actually are. Sometimes the honest answer is that the repair is not worth the
cost of the equipment, and we would rather say it than sell around it.

## What we never do

We do not fit a used part from another machine and describe it as a repair. We do
not substitute a component of a different rating because it is what is on the
van. And we do not order anything before you have approved a written estimate
that names the part.
